I can't reset the little badge about the mail app icon to show all messages as read. It is showing 3424 messages which is what is on the server but selecting all messages and marking them as read doesn't remove the badge.

That's on an att.net email account.

The second issue I have is the flash/HDR controls are missing from the top of the camera app. I can't find any settings to bring them back. tapping at the top of the screen doesn't bring them back as well.
